HEEL-NAILING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 259,687, dated June 20, 1882.

' Application filed Apn'l 17, 1882. g (No model.)

To all whom it may concern Be it known that I, HENRY A. HENDERSON, of Lynn, in the county of Essex and State of Massachusetts, a citizen of the United States,

5 have invented a new and useful Improvement in Heel-Nailing Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming apart of this specification, in explaining its nature, in which- Figure l is a front elevation of my machine. Fig. 2 is a view, part in vertical central section and part in elevation, lengthwise of the machine. Fig. 3 is an enlarged view of the heel-receiver, templet, and nail-holder, and'the manner of supporting the same, hereinafter more fully described. Fig. 4 is a vertical central section of the mechanism shown in Fig.3, representing the construction. Fig. 5 is a plan view below the line at 00 of Fig. 1. v Figs. 6, 7, and 8 are detail views, hereinafter referred to. Fig. 9 is a view, part in section and part in elevation, of the unshipping or stop-motion mechanism. v

2 This invention is an improvement upon that described in my Letters Patent No. 252,215, dated January 10, 1882, and it relates principally to improvements in details of construction, rather than to principle.

0 A is the frame-work of the machine.

B is the cross-head, which is adapted to be reciprocated by means of the rods 1), the crossbar b, the connecting-bar b the crank 12 and the springs b. The crank and connecting-bar serveto'depress or draw down the cross-head,

and the springs to lift it to its originalposition. I do not, however, confine myselt'to this method of reciprocating the cross-head, but

may use any other suitable mechanism for so 0 doing.

block or carrier 0, to which is screwed or 'fastened in any other desirable manner the aWl-holding block 0, the driver-holding block c, and the top-lift spanker c. The block 0 is moved horizontally on the cross-head to bring the awls, drivers, and spanker successively in place, either directly by hand or by means of a ratchet, c bolted to the sideof the block,

the ratchet-wheel c, and the hand'wheel 0 and their connecting-shaft. 7

The cross-head carries the sliding.

Upon the upperpartofthe block G are formed the notches a, into which the latch 0 which is pivoted to thecross-head and is operated by the handle 0, is adapted to shut automatically when the notch is brought in line therewith, thereby locking the block 0 to the crosshead, and in a position which shall cause the awls, drivers, or top-lift spanker to register.

In order that the sliding block 0 may be returned rapidly to its original position after the spanking on of the top-lift of the heel, or without the latch catching in the notches, I have made the side 0 of the central notch higher than the opposite side, 0 so that the latch on the quick movement of the block does not enter the notch, but rides over it and closes on the top of the surface beyond.

The adjustable stop a attached to the side frame and consisting of a screw, may be used to limit the movement of the sliding block, so that upon bringing the same in contact therewith the latch shall enter the notch for} regis-. tering the awls, and there shall be noliability of the sliding block being moved past it.

Ot'course I may use other registering mech- 7 anism than the device described without de parting from the spirit of" the invention.

The awl or driver holding plates or blocks are adapted to be removed from the sliding block and others substituted for the purposes of size adjustment, and I represent in Figs. 4 and 6 the awl and driver blocks provided with a square stud, 0 which enters a square hole, 0 in their respective supporting portions of the sliding block 0, and the lockingscrew 0 as a means of fastening them in a manner to perm'itof their quick removal and substitution. The top-lift spanker has a similar construction for the purpose of fastening, and for the purpose of vertical adjustment in relation to its supporting portion of the block 0 it has the screws 0, which are screwed into the screw- I holes 0 and by means of which, upon releasin g the locking screw 0, the position of the spanker in relation to the supporting-block 5 may be changed. In lieu of this method of effectin g the vertical adjustment of the spanker,

I may use in place of the stud a large screw adapted to swivel in the spanker and screwing into the sliding block, and a disk or wheel 10o interposed between the spankerand the sliding block for operating the screw. In this event simple guide-pins would be substituted for the screws Any other manner of adjustment, however, may be employed, and as there are numerous ways well known to mechanics of accomplishing the object, I do not confine myself to the especial means described.

The top-lift spanker has upon its under surface a top-lift holder consisting essentially of a spring-clamp adapted to hold the blank by pressure upon its edge, and which is capable of adjustment to varying sizes of lifts. The clamp shown in the drawings comprises the curved spring-arms a c ,\vhicl1 are fastened to the block by the bent arms or supports 0 and the adj ustiu g-screws 0 the arms being shaped to extend upwardly upon the sidesof the spanker-block. I prefer, however, that the arms or supports, instead of being at the front end of the springs, as represented, be near the back, as shown by the dotted lines in Fig, 8, in order that a greater range of automatic adj ust ment be provided the clamp.

In addition to the spring side clamp there may be used the yielding front gage-plate, 0 which is fastened to the block and extends downwardly to a position in front of the springcla-mp, as shown in Fig. 8.

In lieu of the specific construction described, any suitable lift-clamping mechanism capable of adjustment may be used.

The slidingjack D is like that described in said patent. The adjustable screwstop d reg ulates the extent of its inward movement.

Upon the table A of the machine, on a line with thejack and behind it, is the bracket E, which is secured thereto in a manner to permit of its horizontal movement thereon in relation to the jack for the purposes of adj ustment. This bracket supports the yielding table E, upon which the templct E and nail-holder E are arranged to slide, as hereinafter dcscribcd, and a heel receiver or guide,E*, for receiving the heel end of the last or other support of the boot or shoe as the jack is moved into position, whereby the heel end of the boot or shoe is caused to assume the proper position in relation to the other operative devices and for gaging and guiding the placing of the heel-blank.

The yielding table E has the vertical plate or standard 0, which is secured by side gibs to the front of the bracket E, in a manner to permit of its vertical movement thereon, and the table is adapted to be lowered or depressed by means of the lever c, pivoted at 0 and an arm, 0 and to be automatically lifted by the coiled spring 0 which surrounds the rod 0 and upon which rod the table moves vertically, or which is fastened to the table and moves vertically with it in a socket at its lower end. A spring-catch, c, and a latch, 0 (shown in Fig. 2,) serve to look the table in its lowest position against the stress of the sprin The table carries the sliding plate a, which is arranged to be moved horizontally to and from the line of reciprocation of the awl in suitable ways or guides by the handle c and the adjustable screw-stop 0 limits the extent of the forward movement, and any suitable stop the limit of the reverse movement.

Attheforward end of the plate is the templct E Upon the templct-carrying plate or slide is the sliding plate a, which is arranged to be moved horizontally on the templct-plate. It has the slot 0" through which the handle 0 passes, and which, in connection therewith, limits the extent of the movement of the said plate. It supports or carries at its front end the nail-holder E. The perforated plate 0' is attached to the bottom of the nail-holder to slide thereon in closing and opening the holes therein, and by means of the projection e and the spring is automatically actuated in the act of moving the nail-holder to and from its position over the templct, the spring moving the plate forward so that the holes are covered, anda projection upon contact with the edge c of the templct acting as a stop in preventing the further movement of the plate, while the nail-holder is still further moved to bring the holes in line with those in the templct. This stopping of the plate of course causes the compression of the spring, and upon the reverse movement of the nailholder and its plate the spring moves the plate back to its original position to cover the holes.

The front of the plate or standard 0 has an opening,in which is the block a", which is fastened to the bracket I and supports the heelreceivcr arm 0 This arm has the slot 0 and is fastened to the block by the bolt 0 and is thereby made vertically adj ustablc thereon. The heel-receiver is curved to approximate the contour of the heel, and has fastened to it the yielding curved spring-arms a, which are adapted to embrace thecountcr of the boot or shoe, and the curved yielding spring'arms e which are adapted to locate, or assist in locating, the position of the heel-blank upon the heel of the boot or shoe, and in some instances to grasp and support it thereon during the nailing operation. The lower pair of these yielding arms preferably are attached to the outer ends of the holder, their inner ends being free, while the upper arms are fastened preferably at their rear end to the rear of the holder, leaving the front ends free, or in a position to be adjusted horizontally in relation to the sides of the receiver by set-screws.

The start and stop motion mechanism is somewhat different from that described in said patent. The connecting-bar b has the pins 1) upon its lower end, which play in vertical slots b and thereby guide the movement of the end of the bar, which is constantly reciprocating. The latch I), which forms the operative connection between the end of the bar and the cross-bar, the position of which determines whether the cross-head shall be reciprocated, is moved upon its supporting plate or bed Z) by means of the lever b connecting-rod b, and arm b. These parts really constitute a lever, the fulcrum of which is at D The lower end of the arm b has the curved slot b, in which the pin Z1 forming a part of the latch, projects. The upper part of the slot is vertical, and the lower part is curved or inclined inwardly. When the latch is unshipped it isin' the position shown in Fig. 2. The movement'of the lever b to bringthe latch under the connecting-bar moves the lower end of the arm I) to the position shown in Fig.9, and the downward movement of the latch causes the pin b moving in the slot b, to throw back the lever 11 to its original position, (see'Fig. 2,)

whereitislocked by springing behind the catch nal position.

1), (see Fig. 5,) and upon'the upward movement of the latch the pin traversing the slot from its lowest point draws the latch. back from beneath the connecting-rod to'its origi- The lever b is made to bear against the edge I) of the slot 1) in the bedplate A, so that it automatically shuts behind the shoulder or catch b.

v The work-support consists of-the metal heelpiece F and the front piece, E, which is fast- ,ened to the heel-piece by a stud, f, upon which it has a slight swiveling movement.

It is intended-that the machine be run by a man and a boy, and its operation is as follows: The boot or shoe is adjusted upon the worksupport and moved to the receiver and the heel-blank placed in position. The templetplateisthen moved horizontally overthe blank, and is then by the lever moved downward thereon and locked automaticallyin that position. The awls are then brought in line with the templet and the machine put in operation,

making one revolution, driving the awls through the templet into the heel-blank and withdrawing them. The awls are then moved, bringing the drivers in position over the templet, and the nail-holder, which has previously been charged'with nails, is moved over' the templet, and the nails discharged into the templet-holes and the holes in the templetblank. The nail-holder is then withdrawn and the machine again set in operation, causing the drivers to drive the nails into and through the heel and into the out and in soles, clinching them upon the metallic support. The naildrivers are then moved, and thelift-spanker, which has been provided with a lift, is moved over the heel, the templet is withdrawn, and the machine is again set in operation and the top-lift spanked on the heel.

Of course the heel-blank may be compressed during the operation of forming the holes or driving the nails, or by both, and it may be still more compressed upon applying the toplift, as the nails may be driven flush with the top of the heel-blank, and by further compression will still further solidify the heel-blank,

and cause the tops of the nails to be exposed sufficiently to penetrate and hold it.

It will be noticed that the devices for holding the templet and nail-holder are arranged back of the line of reciprocation of the crosshead, and that the templet has a direct horizontal movement upon its support, and that the nail-holder also has a direct horizontal movement. This arrangement of these parts and manner of operating them is an improvement upon that described in my said Letters Patent, because it brings them where they can be more readily handled by the assistant, and where they are out of the way of the principal operator and are always in view of the assistant.

. The lower surface of the templet may have spurs or projections z, as represented in Fig. 4, if desired, and I find that it is a convenience to use them, because they close upon and into the upper surface of the heel-blank, and hold it firmly and solidly during the driving of the airls and nails. When heel-blanks of comparatively soft or tempered leather are mit ofit, the awls may be dispensed with and the nails driven through the heel-blank by the drivers without first puncturing it.

In my said Patent No. 252,215 I have shown and described a reciprocating cross-head carrying a gang or group of awls, a gangor group of drivers, and a lift-spanker, which areadapted tobe brought successively into proper position in relation to the work, and I therefore simply claim as novel, so far as this feature ofthe invention is concerned, only the specific means for providing the awls, drivers, and spanker, or two of them, with horizontal movements upon the cross-head; and in this connection it may be stated that an equivalent for the horizontal movement of the carriage on the cross head, as herein indicated, the work-support or jack can be moved horizontally into position under the awls, drivers, or spanker, and the latter be stationary upon the crossh'ead. v
